REFRIGERATOR.

. Application mea 'April 22 My invention relates to improvements vinrefrigerators particularly, though not eX- clusiVely,-for domesticpurposes.

An object of the invention is to provide a simple and elicientrefrigerator including simple and effective means for Ventilating thesame. 1, ,f

A further Object is to supply such ve'ntilating means, the same being soassociated with the refrigerating medium as to set up ventilation in therefrigerator by gravity.

Another object is to provide Ventilating means, as above, arranged tostimulate the circulation of air in the produce compartments, also tonrnimize humidity from accumulations of dondensations therein and,further, to utilize compartment ypartitions in the structure of saidVentilating means.

With the foregoing and other objects in lView, which will appear in thefollowing description, the `invention resides in the novel combinationand arrangement of parts Aand in the details. of constructionhereinafter described and claimed. a

In the drawings, Fig 1 is a Vertical central sectional View of arefrigerator embodying my invention; Fig. 2 is a horizontal sectionalview thereof,the same beingI taken on the line 2-2 ofy Fig.- 1 and Fig.3

is a Vertical sectional View taken on the line 3-3 of Fig. 1.

Reference bein had to the drawing, it will be Observed t at my improvedrefrigerator includes the usual box-like cabinet A comprising a bottom10, ends 11, front with doers 13 therein', v'back-14 and top 15, whichcabinet is supplied with an inner lining 16 insulated, as at 17, fromsaid parts of said cabinet. Within the cabinet is a hollow partition B,L-shaped in Vertical cross section, and consisting of anupright branch band a horizontal branch 'b'. This partiton 'B provides a compartment Cin an upper corner of a provision chamber D encased by the cabinet. Theupper extremity of the upright branch b of the partition B falls shortof the top Of the cabinet providing an elevated port 18, affordingcommunication between the upper portion of the provision chamber D andthe upper portici of the refrigerant compartment C. The eX- tremity' ofthe horizontal branch b of the partition B falls short of the adjacentend wall of the lining 16 providing a portk 19 affording communicationbetween the lower portion of the refrigerant compartment C 1926.

and the bay in the provision chamber neath saidhorizontal branch b.

The upright branch b of the hollow partition B lconsists of two spacedwalls 20 and 21, while the horizontal branch b of said partitionsconsists of spaced trays 22 and 23, the upper tray 22 branching olf fromthe wall 2.0 and the lower tray 23 from the wall 21. These Walls 20and2l and trays 22 and 23 form between them an air passageway the cabinetfrom front to back. The space between the Walls 20and 21 at the 'upperedges thereof is spanned bya cap-piece 24: through which theflower endof an upright air ingress duct 25 opens. This duct eX- tends through thetop 15 of the cabinet bringing the upper portion of the air passageway Ein the partition B into communication with the outer air. way E isunobstructed at the extremity the horizontal branch of the partition B,said passageway, at this point, (opening into the duct 19 between therefrigerant compart- 90 nient (l and the provision chamber D.

Between thev walls 20 and 21 of the parl tition B is an upright egressduct 26 cpening at its upper end near the ceiling o the `provisionchamber D, the lowerend of said as duct opening outwardy through thefront 12 of the cabinet into the outer air. n A suitable air chillingmedium, shown) such as ice or any of the conventlonal freezing units isplaced within the refrigerant comartment C. In the presence of achilling medium so disposed, an internal circulation of air is set upwithin the cabinet by gravity, such circulation being accompanied withVentilation, also by gravity, through the ipgress of air to the cabinetand the egress of nair therefrom. The cycle' of the air in its internalcirculation Within the cabinet may be traced beginning in therefrigerant compartment C, where the air, cooled by the refrigerant,descendsV byA gravity throughv the port 19- into the pro,-m

\vision chamber D. Heated in chamber' D' by the provisions and along thewalls 'of .said chamber, the air rises `tO-the upper portion of thechamber and thence flows throu h the port 'p18 into the upper portion oft e refrigerant compartment C,lwhence the cycle 'is completed. In thepresent connection, it will be noted that the port 19, disposed .i alongthe end wall of the interior of the cabinet, providesior a thoroughcirculation E traversing the interiorl of Said air passageof air .inthat portion of the provision chamber D beneath the refrigerantcompartment C, no dead air being permitted to stand in said portion ofsaid chamber. To comprehend the movement of the air in ventilating thecabinet, it must be understood that the wall 20 and tray 22 of thepartition B are chilled by the refrigerant in the compartment C. The airin the passageway E, in turn being cooled by said wall 20 and tray 22,fiows out of said passageway into the port 19 throughv which thecirculating stream of air is passing the air {iowing from saidpassageway E being replenished with fresh air entering through the duct25. Coincident with such ingress of fresh air to the interior of thecabinet is the egress of air therefrom, the same taking place in theegress duct 26. This egress duct being cooled through the wall 20,under` the influence of the refrigerant in the compartment C, results inthe cooling of the air in said duct 26. Said air thus affected flows bygravity out of the duct 26 to the outside of the cabinet, the same beingfollowed by air entering the upper end of said duct. f The provision ofthe air passageway within the partition B is advantageous 1n that theincoming of fresh -air therein in a measure insulates the wall 20 andtray 22 from the wall 21 and tray 23 keeping the former wall and traycomparatively dry and thereby minimizing the percentage of humiditywithin the cabinet. Further, the wall 21 thus insulated from the wall 20and affected by the incoming air is relatively warm, the result beingthat the upward movement of air in the provision chamber D along saidwall 21 is stimulated as opposed to being retarded were said wall to berelatively cold.

`Condensation accumulating in the lower pan 23 is conducted from thecabinet through a main drain pipe 27. Likewise, condensationaccumulating in the upper pan 22 is led away through astub pipe 28,whichempl ties into said main drain pipe 27.
